COD MW 2016 remaster help

Hello fellow redditors. First post here. I tried to find a lot of solutions but couldnt find any fix for it. I downloaded COD Modern Warfare 2016 remastered from 3 sites. Fitgirl, Ankergames, steamunlocked. everytime i play the game after completing the mission "Charlie Dont Surf" either the game crashes or it hangs on 90% loading screen of the next mission. Please help me i havent been feeling good lately and this is a very nostalgic game for me and i really want to relive this game again.
